Nick,
I remember some years ago searching for a small wooden bowl of a size for making only a small amount of dough and was appalled by the prices of the bowls I found from my searches. Can you tell us how much your dough trough cost? And is the wood treated in any way?

Yeah, sure. The bowl costed $275 with shipping (which was $50 from south carolina). the price tag on the bowl said $250 when i got it, so it looks like i somehow saved $25. Sounds like a lot, but it's carved out of one piece of wood, and it takes months to finish. he quoted me 2-4 months if he made it to my specs (which he also said he didn't do bowls exactly to measurements, just "close"). Not to mention this bowl is huge! I think of it as a work of art that is also very functional. And it beats the heck out of the cost of a mixer, and will last a heck of a lot longer! Van gave me a lifetime guarantee, though he was sure to mention lifetime being his lifetime, and not mine

I asked him how to treat it and he said to wash it wash it like 4 times a year, making sure not to submerge it in water. After washing, I'm supposed to rub it down with mineral oil. It doesn't feel shellacked, so I'm assuming it's just rubbed down with mineral oil.
I'm with Don. Don't see the advantage. But throw some flour and water in with your child and let him go nuts.
That would be a marketing pic! 
I measured the counter space I have in my kitchen for making dough and it's 25"x18". mixing a 25 lb bag of flour into dough on that surface with no side walls is not something I want to play around with. The dough trough can go anywhere, as well. It just made sense for my needs.
I gotta start my boy helping out sometime. He can't chop wood yet. Toss him in the dough bowl and let him have at mixing some dough! I can just imagine the chaotic mess that would ensue
